operate.)
Poor

outlet.
Install

it.
Bucket is full. If Auto Shut Off lights, empty the bucket
and replace properly.
Humidity control is at Off position Turn the humidity control switch toward
Max.
Wire disconnected or loose Connect wire. Refer to wiring diagram for
terminal identification. Repair or replace
loose terminal.
Capacitor. Test capacitor.
(Discharge capacitor before testing.) Replace if not within +10% of
manufacturer's rating. Replace if shorted,
open, or damaged.
2. Motor runs but compressor does not Voltage (115V + 10%) It must be between 103.5V and 126.5V. If
run. not within limits, call an electrician
Wiring Check the wire connections; If loose,
repair or replace the terminal. If the wires
are disconnected, refer to wiring diagram
for identification, and replace the wires.
Check the wire connections; If not
according to the wiring diagram, correct
the connections.
Rotary switch Check for continuity, refer to the wiring
diagram for terminal identification. Replace
the switch if the circuit is open.
Defrost control The Defrost Control senses frost build-up
on the evaporator coil and automatically
shuts off the compressor. The fan
continues to run, drawing air across the
coil, and melting the frost. When the coil is
defrosted, the compressor automatically
restarts, and dehumidifying resumes.
Capacitor Check the capacitor.
(Discharge capacitor before servicing.) Replace if not within +10% of
manufacturer's rating. Replace if shorted,
open, or damaged.
Compressor Check the compressor for open circuit or
ground. If open or grounded, replace the
compressor.
Overload protector (OLP) Check the compressor OLP if externally
mounted. Replace if open. (If the
compressor temperature is high, remove
OLP, cool, and retest.)
3. Does not defrost control. Defrost control is defective. Check defrost control, replace it.
4. Insufficient dehumidification Low relative humidity Turn dehumidifier off.
Poor air circulation Move dehumidifier to obtain free and
unobstructed air circulation.
H/E clogged with dust and dirt Clean evaporator and/or condenser assembly
Air filter is dirty.
Motor is not operating. Check Motor, repair or replace it.
